Cordierite honeycomb ceramic is made of synthetic cordierite raw materials, adding bonding agent and firing loss agent, after mixing and mixing, mud, extrusion, drying, and firing at 1280 ~ 1320℃.
Its characteristics are that the raw material used in forming is synthetic cordierite raw material, the forming process is extrusion process, and the drying is combined with tunnel type shaping drying and box type drying furnace. The preparation method includes the following steps: wet grinding clay, talc, alumina, light burning magnesium powder in ball milling to less than 320 mesh powder, ball milling powder after pressure filtration and vacuum mud, the billet is synthesized in the flame kiln as cordierite material; Then the synthesized cordierite is finely ground again to the required size; Then the finely ground cordierite powder is added with MC or PVA as the main component of the adhesive, and the honeycomb ceramics can be produced by extrusion process. Mainly used in automobile exhaust catalytic purification, industrial furnace dust storage heat, petroleum catalytic cracking and other industries.
